The metabolic effects of adenosine on regionally ischemic myocardium were investigated in an open-chest rabbit model by means of phosphorus 31 nuclear magnetic resonance (NMR) spectroscopy. Sixteen anesthetized New Zealand white rabbits were subjected to thoracotomy; a reversible snare occluder was placed around a large branch of the left circumflex coronary artery, and an NMR surface coil was ...

We report a high-throughput (HTP) nuclear magnetic resonance (NMR) method for analysis of media components and a metabolic schematic to help easily interpret the data. Spin-lattice relaxation values and concentrations were measured for 19 components and 2 internal referencing agents in pure and 2-day conditioned, hormonally defined media from a 3-dimensional (3D) multicoaxial human bioartificia...

All reactions were carried out with magnetic stirring under an atmosphere of argon in oven-dried glassware. Methanol was purchased from Sigma-Aldrich and stored in an anhydrous atmosphere. Sodium acetate was purchased from Aldrich and stored under anhydrous atmosphere. H NMR spectra were recorded on Varian 400 MHz spectrometer at ambient temperature or a Bruker Avance III 500 (500 MHz). Data is...

Methods: Neonatal rats (n = 5, 7-28 days old) were anesthetized by -chloralose and fixed to a specifically designed holder. The volume of interest (3 x 2 x 4 mm) was centered in the left hippocampus. H NMR spectra were measured at 400 MHz (9.4T) on a Varian/Magnex spectrometer using an ultra-short echo-time STEAM sequence (TE = 2 ms) with VAPOR water suppression and outer volume saturation [5]....

Experimental Section Equipment. The UV-light triggered reactions were performed in a Rayonet Chamber Reactor with UV-lamps having their maximum intensity located at a wavelength of 253 nm. We used varying illumination times as detailed (vide infra). The temperature in the reactor was stable at T = 22 ºC. Solution 1 H and 13 C NMR spectra were recorded on a Bruker 300 MHz spectrometer with tetra...

A Bruker Avance 200 NMR Spectrometer was used to perform simple quantum computations on a two quantum-bit (qubit) bulk system of CHCl4. Base states |00〉 were created through the process of temporal averaging. The logic of the controlled-NOT (CNOT) gate was observed and used in the application of the Deutsch-Josza and Grover algorithms. The Deutsch-Josza algorithm was successfully used to determ...

Some unsaturated compounds with the required (Z,Z)-double bonds configuration are synthesized through controlled ozonolysis process of 1,5,9-cyclododecatriene by determining the necessary amount of ozone passing through to selectively guarantee the breakage of a double bond while leaving other two bonds as (Z,Z). The products were diagnosed by using NMR spectrum, infrared (IR) and mass spectrom...

Syntheses of organometallic initiators were conducted under a nitrogen atmosphere using standard Schlenk techniques. All reagents were of commercial grade and obtained from Sigma-Aldrich Co.. Solvents and the propionic acid used for the preparation of initiators were carefully dried and distilled under nitrogen atmosphere prior to use. TEMPO was sublimated and stored under nitrogen atmosphere. ...
